Need help distinguishing Class I from Class II

  1. Need help distinguishing Class I from Class II

    I know that Class I compounds act directly on the androgen receptor, and Class II compounds don't. Would that make all Class II compounds progestins? If anyone could point me in the direction to find out different compounds binding affinities I would be eternally grateful.

    I've seen articles and listings before, but they are always in random places and every time I need to figure it out it's like a 4 hour process trying to find out which compounds bind to which receptors.

    Here's the deal: I have 2 bottles of P-Mag, 2 bottles of X-Mass (tren, 1-dienelone, w/e), 1 bottle of the 020907 trenadrol (is there a verdict on this yet?) and 1 bottle of SD-max (superdrol clone)

    My memory wants to tell me that the dienolone compounds bind more readily at the androgen receptor than testosterone, so I want to say they are Class I, I BELIEVE halodrol was a class II, so I would guess P-Mag would be as well, but I'm not sure. Superdrol I'm pretty sure is a Class I. And if trenadrol resembles 1-dienolone as PA and others are saying it does, I would imagine it has a high affinity for the androgren receptors as well.

    If I'm off base please tell me because I'm trying to put together a fall cycle and have been having trouble finding the binding affinities ANYWHERE as of late.

  2. Class I = binds to androgen receptor
    Class II = does not

    Class I

    Boldenone based - 1,4AD & Bold
    Progestin based - (similar to trenbolone) - Trenadrol & Trenaplex
    Dienolone based - (again similar to tren) - Mdien
    Mepitiostane (Thioderon) based - Epistane & Clones (like Havoc & so on so forth)
    Desoxymethyltestosterone/DMT (Madol) based phs - Pheraplex & clones
    DHT (Dihydrotestosterone) based phs - M5AA

    Class II

    Masteron (Dromostanolone) based - Superdrol & Clones
    Oral Turinabol (Dehydrochlormethyltestosteron e) based - Halodrol & Clones
    Dianabol (methandrostenolone) based - M1,4ADD, M1T, 1-T, Methyl XT
    Winstrol (stanozolol) based - Winztrol, Orastan-A, Furaguno, etc
    Furazabol (miotolan) based - Furazadrol etc
    Progesterone based - Revolt, Propadrol, Max LMG
    Clostebol based - Chlorodrol, Oxyguno

  3. Thanks a ton, but I'm having trouble analyzing some of the data you posted. Wouldn't all winstrol based PH's be DHT derivatives? and DHT derivatives are all supposed to be Class I according to that listing. And what is the difference between progesterone based compounds and progestin based compounds? If I could get someone to school me on those 2 issues that would be awesome. I appreciate it again tho SC.

  4. not my area of expertise sorry, all i had was that page.

  5. subbed for more info on this.

    x2, very interested

  7. subbbbbbb, been looking for that list for a long time. The classes should be attached to the Steroid Profiles sticky.
    The Truth is, there is no Truth.

  8. I thought 17a reduced were class 2... ie phera, sd, epi... Read somewhere

  9. But there is lots of people that debate this class 1 class 2... Williams pretty much ranked inj class 1 and orals class 2.

  10. And u list 4AD as class 2??? It's a ph to test so makes it class 1 right?

  11. somebody page Dr.D......

  12. progesterone= a natural hormone the body makes
    progestin= a synthetic form of progesterone

  13. glad to see I'm not the only one who doesn't have a tight grasp on everything there is to know about this stuff haha..thanks for those links lennox..I've never understood the action of progestins very well.

  14. I'm curious and ready to learn, bump.

  15. this forum has offcially been stumped. im interested as well if anyone can figure this out. there has to be atleast a couple ppl who knows this.

  16. Hmmm Ive heard this theory was bunk

  17. I've always wondered what data this idea was based on. If something is not binding to androgen receptors, how exactly is it mediating it's effects on muscle? It seems like any anabolic hormone effects on muscle would have to involve androgren receptors, GH receptors, IGF-1 receptors, or insulin receptors.
    In my years of studying biochemistry and mechanisms of muscle hypertrophy, these are really the only mechanisms I have come across.
